Emission spectroscopy is a spectroscopic technique which examines the wavelengths of photons emitted by atoms or molecules during their transition from an excited state to a lower energy state. Each element emits a characteristic set of discrete wavelengths according to its electronic structure, and by observing these wavelengths the elemental composition of the sample can be determined. read more

Best Answer: Emission and absorption are opposites. Emission refers the a decrease in the energy of the atom from a higher state to a lower state and vice versa for absorption. In this case, there are 6 answers. 3 for the first, 3 for the second. read more
